The plugin's SyndicatedPost::sanitize_content() function only strips the 'target' attribute (the lines that would strip 'style' and 'on[a-z]+' event-handler attributes are commented out), and SyndicatedPost::insert_post() deliberately removes WordPress's wp_filter_kses and wp_filter_post_kses filters from content_save_pre before persisting imported feed items via wp_insert_post(). This makes it possible for unauthenticated attackers who control an external feed that a site has already subscribed to to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.","published":"2026-10-31T09:16:32.933","modified":"2026-10-31T09:16:32.933","cvss":{"score":7.2,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/feedwordpress/"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/feedwordpress/tags/2026.0517/syndicatedpost.class.php#L1196"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/feedwordpress/tags/2026.0517/syndicatedpost.class.php#L1726"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/feedwordpress/tags/2026.0517/syndicatedpost.class.php#L395"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/feedwordpress/tags/2026.1016/syndicatedpost.class.php"},{"type":"WEB","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/cad2334c-21f5-40bc-8b08-32c12ce1e077?source=cve"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-10-31T09:16:32.933"}}
